Application filed December 30, 1968. Serial No. 70,080.

To all wzomfit may concern."

Be it known that l, ALEXANDER l. Joni DAN, a citizen oi the United States, and resi dent ci Madison, in the county ol' Dane and State of l'fisconsin, have invented certain new andV use-ful improvements in Streetlndi'cators; and l do hereby declare that the following is a full, clear, and exact description thereof.

The object of my present invention is to provide simple and eiticient street-indicators for oars or similar public. eonveyances, the construction and arrangement being such as to eliminate all springs or lilre parts subject to wear as well as to insure accurate leed, Whereby the naine indicating; the cross-streets is i'ully displayed to the occupants oi the vehicle. The invention therefore consists in certain peculiarities of construction and combination ol parts as hereinafter set forth with reference to the accompanying; drawings and subsequently claimed.

ln the drawings: Figure l represents a lo'i'uritudinal sectional vieuT oi a street-indicator embodying; the features of my invention, 'Fig 2, a. side elevation of the same showing` the independent.driving gear for the rolls, which driving-gear embodies the essential features ol` my invention; Fig. 3, a plan view ol' the street-iinlicator, with parts broken array and parts inV section to better illustrate the invention; Fig. 4l, a detail face vieu' ol a preferred forni of apron, and 5, a sectional vicav ol' the saine,'as indicated hy linef55 ol' the precedinggure.

Referring by numerals to the drawings, l indicates a base having secured thereto parallel side standards 2, which standards are provided with alined bearings 'lor the reception oi metallic shal'ts 3 ol rollers 4 and respeetively. lilac-h roller has lastened thereto an end of an apron G, which apron passes from the roller 4 under a guide-roller 7 and over a feed-roller 8 to roller, upon which latter roller, as shown in Fig. l, the apron is fully Wound. The longitudinal edges of the apron G are provided with a series ofY grornets equally spaced apart and adapted to'engage series ot' spur-teeth that project from opposite ends of the leed-roller. The feed-roller shalt E) is mounted in bearings 'formed in the standards, said leed-roller being forward of the apron-'roller 5, and arranged to project into an aperture in an end of the car-frame, as shown. Street names are imprinted upon the apron are displayed g upon that portieri of the same vih-ich partly surrounds the aforesaid iced-rollerin practice, it is desiralile to prf street-indicator with a hood or casita; indicated by dotted lines in hilf. l the ca Y beingr slotted at the point whcreit partly si rounds tl'e leed-roller, through which slot i street names are visible to the oeeupr-nts olf of the indicator is secured to the roel ol' the vestibule of the vehicle or car and i to the ventilator extension thereoi'.' the iced-roller shalt Sl a friction-d' against the opposite faces or which d fitted a pair ol' sprocket-wheels l2 and l. same being loosely mounted upon. said sh: Coil-sprinrs le surround the shalt .in s interposed between rollers l5 and l hubs ol the sprocket-rxhcels, wh latter are held against the Al'rictionef` the desired tension. The collar l: l against lateral play by the adjacent standard 2, while the collar i6 is last upon the end oi the shalt 9, it beingr understood that it desired both of these collars may be adjust set upon said shalt 'lor the purpose ci regulatine the tension of their respective springs, this feature however being within `ie kno .i edge of skilled mechanics, and loriA part of the invention.

The shafts 3 of rollers 4 and are respectively provided with sprocket-wheels (not shown) which.

similarheads secured to the opposite ends f. said rollers, thereby constituting guides 'for the apron. The ratcl'ret-Wheels and vpan'ls thus constitute right and left clutchaneinbers in connection with the winding-rollers, *Whereg directions. The end of the feed-roller shalt Sl, opposite the sproclretarheels, is provided with a. nevel-pinion 241, which meshes with a similar bevel-pinion 2G, Twhich drive-shalt is mounted in bearingl lugs extending from the adjacent standard,

the vehicle, it being understood that the hase llaneed heads 22, 23 of the collars, there heir f 25 last on a drive-shaft 'L05 by the latter are positively driven in opposite As shown in lFigs. 4 and 5, the apron mayV lbe provided with cross-lags 27 placed'at suitable intervals apart in order `to add rigidity to said apron and. prevent buckling of thesame as it is coiled upon the rollers.

When the arts are in the position, as shown in liigl, t e indicator must be reversed, and I as indicated by the arrow, motion being imparted to the feed-roller 8,Will cause roller4 to be put in motion to rewind the apron thereon. For example, if 'the feed-roller is rotated so as to move the apron two inches atveach intermittent move-ment of the driveshaft, this length iswound by the chain and sprocket-gear' upon roller 4, the portions of the drivingear and roller bein such as to insure t e take-up,which ta e-up would in this instance require the maximum movement of said roller 4. It follows that while the winding-movement takes place with relation to roller 4, roller 5 will only make its minimum rotary movement in order to release the two inches of apron, and consequently the. chain and sprocket-drive of said roller 5, while moving its full distance in the direction indicated by the arrows, will run ahead of the aforesaid rolle-r 5, due to the pawl and ratchet-wheel connection. As the a ron coils increase upon the roller 4, it is evident that the maximum drive imparted to said roller' will bein Lexcess of the movement r'e uired. This excess is compensated for by t e friction-clutch connection of the sprocket-wheel 12 and disk 11, which connection permits a slip ,of said .procket-wheel at the instant the apron-is awn taut. Thus it will be understood that the same effect is obtained when the apron is being wound upon the forward roller 5, the drag springs 28 in either case being provided I vto prevent over-run of that rollerfrom which the apron is unwinding, until such time as the coiled apron has been reduced to a diameter approximately the same size as the roll, at whrch time the ratchet-wheel and pawl will move in unison.

FromA the foregoing it will be seen that each apron-rolleris provided with an independent driving-gear, whereby motion is received from the feed-rollerfand each driving- A pro-k 1. Aistreet-indicator for vehicles, cornprising standards having a pair of windingrollers mounted therein, an .a ron itted to the winding-rollers adapted to be alternately wound from oneroller to the other, a righthand clutch-member in connection with one ,of .the Winding-rollers, a left-hand clutchmember in connection withthe other winding-roller, sprocket-wheels carried .f by the clutch-members, a feed-roller, a shaft for the feed-roller, the shaft being mounted in the standards in 'advance of the Winding-rollers, a friction-disk secured 'to the feed-roller shaft, spring-pressed sprocket-wheels loosely mounted upon said feed-roller shaft in engagement with the faces of thedisk, and chain-belts connecting the spring-pressed sprocket-wheels, and the sprocket-wheels carried by the winding-roller clutch-memers.

2. A street-indicator for vehicles comprising standards having a pair of shafts mounted therein, fianged headed windingrollers secured to the shafts, a ratchet-wheel loosely mounted upon each shaft, the ratchetwheels being provided with' oppositely inclined teeth, respectively spring-controlled' pawls carried by the Winding-roller heads for' engagement with said ratchet-wheels, a v

feed-roller, a shaft for the feed-roller, the shaft bein mounted in the standards in advance of t e Winding-rollers, a friction-disk secured to the 'feed-roller shaft, spring- 'pressed sprocket-wheels loosely mounted upon sai feed-roller shaft in engagement with the faces ofthe disk, and chain-belts connecting the spring-pressed sprocketwheels and the sprocket-wheels fcarried by the winding-roller shaft. y

In testimony that I claim the foregoing I have hereunto set my hand at Madison, in

`the county of Dane and State of l/Visconsin in the presence of two Witnesses. ALEXANDER P. JORDAN.
